๐Ÿ”’ 89 Million Steam Users at Risk After Third-Party Vendor Hack!

A serious data breach has shaken the Steam community, potentially affecting over 89 million user accounts. While Steam itself wasnโ€™t directly hacked, a third-party vendor that Valve previously worked with has been compromised, and the stolen data could include usernames, passwords, 2FA logs, and more.


โš ๏ธ What Happened?

  • ๐Ÿ’ฅ A hacker named โ€œMachine1337โ€ posted on a darknet forum claiming access to 89+ million Steam records.
  • ๐Ÿ“Š The leak reportedly includes:
    • Usernames and passwords
    • Two-factor authentication (2FA) SMS logs
    • Message metadata and delivery details
  • ๐Ÿง  This breach was brought to light by security group Underdark AI via LinkedIn and further amplified by Reddit user Mellow_Online1.

๐Ÿงฉ How Did This Happen?

  • ๐Ÿข A third-party cloud service provider used by Valve, likely for SMS 2FA services, appears to be the breach source.
  • โš™๏ธ These services are common for handling 2FA verification messages, but this hack could allow malicious actors to:
    • Intercept real 2FA codes
    • Send spoofed or phishing messages
    • Exploit reused credentials across platforms

๐Ÿ›ก๏ธ What Should You Do NOW?

  1. Change your Steam password immediately.
  2. Enable Steam Guard (two-factor authentication) if you havenโ€™t already.
  3. NEVER trust a 2FA message you didnโ€™t request.
  4. Avoid reusing passwords across websites โ€” leaked credentials are often used in credential stuffing attacks.
  5. Consider using a password manager to generate and store strong, unique passwords.

๐Ÿ“Œ Stay Alert

Valve has yet to issue an official statement, but given the scale of the breach, itโ€™s crucial to act now. Always verify login attempts and be cautious of suspicious messages claiming to be from Steam or Valve.
